Efficacy of treatments and pain management for trapeziometacarpal (thumb base) osteoarthritis: protocol for a systematic review

Investigating Molecular Signatures Underlying Trapeziometacarpal Osteoarthritis Through the Evaluation of Systemic Cytokine Expression

Purpose

Non-operative management of trapeziometacarpal osteoarthritis (TMOA) demonstrates only short-term symptomatic alleviation, and no approved disease modifying drugs exist to treat this condition. A key issue in these patients is that radiographic disease severity can be discordant with patient reported pain, illustrating the need to identify molecular mediators of disease. This study characterizes the biochemical profile of TMOA patients to elucidate molecular mechanisms driving TMOA progression.

Methods

Plasma from patients with symptomatic TMOA undergoing surgical (n=39) or non-surgical management (n=44) with 1-year post-surgical follow-up were compared using a targeted panel of 27 cytokines. Radiographic (Eaton-Littler), anthropometric, longitudinal pain (VAS, TASD, quick DASH) and functional (key pinch, grip strength) data were used to evaluate relationships between structure, pain, and systemic cytokine expression. Principal Component Analysis was used to identify clusters of patients.

Results

Patients undergoing surgery had greater BMI as well as higher baseline quick DASH, TASD scores. Systemically, these patients could only be distinguished by differing levels of Interleukin-7 (IL-7), with an adjusted odds ratio of 0.22 for surgery for those with increased levels of this cytokine. Interestingly, PCA analysis of all patients (regardless of surgical status) identified a subset of patients with an “inflammatory” phenotype, as defined by a unique molecular signature consisting of thirteen cytokines.

Conclusion

Overall, this study demonstrated that circulating cytokines are capable of distinguishing TMOA disease severity, and identified IL-7 as a target capable of differentiating disease severity with higher levels associated with a decreased likelihood of TMOA needing surgical intervention. It also identified a cluster of patients who segregate based on a molecular signature of select cytokines.

Intervention reporting and dissemination of information for the management of hand osteoarthritis

INTRODUCTION

A variety of exercise programs are recognized to be effective for the management of hand osteoarthritis (HOA). It is important to report the essential elements of these exercise programs for clinicians to replicate properly and facilitate their implementation with individuals who suffers from HOA, especially if they are found to be effective programs.

PURPOSE OF THE STUDY

The objective of this article was to assess content reporting using three exercise reporting standardized assessment tools among exercise interventions randomized controlled trials (RCTs) involving individuals with HOA.

STUDY DESIGN

A descriptive study was used.

METHODS

Two pairs of trained assessors independently identified, selected, and scored the reporting quality of the exercise programs of RCTs on the management of HOA using three standardized assessment tools: the Consensus on Exercise Reporting Template (CERT) checklist, Consensus on Therapeutic Exercise Training (CONTENT) scale, and Template for Intervention Description and Replication (TIDieR) checklist to review the quality of reporting of 11 RCTs included in a recent Ottawa Panel guideline.

RESULTS

Based on consensus reached by two different pairs of reviewers and an arbitrator, the mean total scores for the 11 included exercise programs were reported as follows: the mean total score for the CERT, CONTENT, and TIDieR was 10.58/19 ± 4.34, 3.27/9 ± 1.90, and 5.92/12 ± 2.54, respectively. The overall Pearson's Correlation (r) between the methodological quality and intervention reporting was 0.86, 0.71, and 0.54 for moderate-to-high RCTs and 0.47, 0.79, and 0.42 for fair-to-poor methodological quality for the CERT checklist, CONTENT scale, and TIDieR checklist, respectively.

CONCLUSIONS

The intervention reporting in the management of HOA is poor among low-, moderate-, and high-quality clinical trials. The least reported information was intervention parameters related to behavior change. Improving reporting is recommended to ensure replication of effective exercise programs to enhance quality of life of individuals with HOA.

Basilar Thumb Arthritis: The Utility of Suture-Button Suspensionplasty

BACKGROUND

We sought to compare the functional outcomes, radiographic outcomes, and complications of trapeziectomy and flexor carpi radialis (FCR) to abductor pollicis longus (APL) side-to-side tendon transfer with or without suture-button suspensionplasty for thumb basilar joint arthritis.

METHODS

Patients treated with and without suture-button suspensionplasty were compared over a 6-year period. Data were reviewed for complications and functional outcomes, including grip and pinch strength, range of motion, and visual analog scale (VAS) pain scores. Plain radiographs were independently reviewed at initial presentation and at final follow-up, including proximal phalanx length, trapezial space height, and trapezial height ratio.

RESULTS

Seventy thumb arthroplasties were performed in 70 patients. Trapeziectomy with FCR-APL side-to-side tendon transfer was performed in 39 patients, and trapeziectomy with FCR-APL side-to-side tendon transfer with suture-button suspensionplasty was performed in 31 patients. Mean length of follow-up was 28.4 ± 3.9 and 23.8 ± 2.6 months, respectively. Postoperative grip, oppositional and appositional pinch strength, and VAS pain scores improved compared with preoperative values, but were not significantly different based on suture-button suspensionplasty. Percentage decline in trapezial space ratio was significantly different between groups at 36.7% and 20.4% for procedures with and without suture-button suspensionplasty, respectively indicating that the trapezial space was better maintained within the suture suspension cohort. The incidence of postoperative complications, including surgical site infection, paresthesias, reoperation, complex regional pain syndrome, and symptomatic subsidence, was not significantly different between groups.

CONCLUSIONS

Trapeziectomy with FCR to APL side-to-side tendon transfer with and without suture-button suspensionplasty results in comparable improvement in pain, grip strength, and functional parameters. Suture-button suspensionplasty results in significantly greater preservation of trapezial space.

Class IV laser therapy for trapeziometacarpal joint osteoarthritis: Study protocol for a randomized placebo-controlled trial

OBJECTIVE

Osteoarthritis (OA) is a chronic and prevalent joint disorder with great impact on quality of life and high economic burden. Although a number of conservative therapies have proven to be effective for the management of hand OA, only modest treatment effects were reported for most individual interventions. The aim of the proposed study is to assess the effect of Class IV laser therapy (LT) on pain and pinch strength in patients with thumb carpometacarpal (TCMC) OA.

METHODS

A randomized, controlled, single-centre, double-blind, clinical trial, with 1:1 allocation ratio, will be carried out involving patients presenting TCMC-OA Grades 1-2 (aged >18 years). Both assessor and statistician will remain blinded. Patients with TCMC-OA will be randomly assigned to the experimental group (will receive LT) and control group (will receive a placebo treatment). Outcome measures will be pain scores at the base of the thumb measured with visual analogue scale (0-10: 0, no pain and 10, worst pain) and changes in pinch strength, both collected at baseline, 4, and 12 weeks. Statistical analyses will be based on an intention-to-treat analysis using the last value forward method. A two-tailed independent Student's t test for the continuous variable of age and baseline scores will be used for comparison of baseline characteristics and outcome variables. Paired Student's t tests will be used to determine the level of significance of the differences between the pretreatment and posttreatment measurements of the individual groups. Repeated measures analysis of variance will be used to determine the differences in time as the within-subjects factor and group as the between-subjects factor.

DISCUSSION

To our knowledge, the results of this study will provide the first double-blinded evidence for Class IV LT in patients with TCMC-OA.

The knitting community-based trial for older women with osteoarthritis of the hands: design and rationale of a randomized controlled trial

BACKGROUND

The prevalence of hand osteoarthritis (HOA) has been reported to be higher amongst women over 50 years old (66%) compared to men of the same age (34%). Although exercise therapy has been shown effective in reducing symptoms and disability associated with HOA, adherence to treatment programs remains low. The primary objective of this RCT is to examine the effectiveness of a 12-week knitting program for morning stiffness (primary outcome) and pain relief (secondary outcome) 2 h post-wakening in females (aged 50 to 85 years old) with mild to moderate hand osteoarthritis (HOA).

METHODS/DESIGN

A single-blind, two-arm randomized controlled trial (RCT) with a parallel group design will be used to reach this objective and compare results to a control group receiving an educational pamphlet on osteoarththritis (OA) designed by the Arthritis Society. The premise behind the knitting program is to use a meaningful occupation as the main component of an exercise program. The knitting program will include two components: 1) bi-weekly 20-min knitting sessions at a senior's club and 2) 20-min home daily knitting sessions for the five remaining weekdays. Participants assigned to the control group will be encouraged to read the educational pamphlet and continue with usual routine. Pain, morning stiffness, hand function, self-efficacy and quality of life will be measured at baseline, six weeks, 12 weeks (end of program) with standardized tools. We hypothesize that participants in the knitting program will have significant improvements in all clinical outcomes compared to the control group. A published case study as well as the preliminary results of a feasibility study as examined through a 6-week pre-post study (n = 5 women with HOA) involving 20-min daily knitting morning sessions led to this proposed randomized controlled trial research protocol. This article describes the intervention, the empirical evidence to support it.

DISCUSSION

This knitting RCT has the potential to enhance our understanding of the daily HOA symptoms control and exercise adherence, refine functional exercise recommendations in this prevalent disease, and reduce the burden of disability in older women.
